| D | README_HW_models.md | 9 The purpose of these models is to provide a good enoug HW model for BLE
24 Overall these models have a time granularity of 1us.
30 using a very nimble engine provided by the native simulator, the "hw scheduler".
34 In reality any action performed by a HW peripheral will take some amount of
38 Such processes will just be implemented as a C function (or a set of them),
41 Other processes do take a considerable amount of time, like for example sending
42 a radio packet, or generating a random number.<br>
43 Such processes will be modelled in a bit more complex way:
46 * When needed these timers will be set at a point in the future where some

9 * A peripheral model, which emulates both the nRF UART and UART-E.
10 * A backend which can send and receive the data somewhere.
19 Each UART can be configured to log to a file the Tx and/or Rx bytes.
22 The first column is a timestamp, in microseconds, when the frame *ended*;
27 The UART also has a test API which allows embedded code to register callbacks to be
28 called whenever a byte is transmitted or received. This callback can replace the byte before
51 Therefore you cannot connect this backend to a console, or real devices.
60 The backend will also realize about a possible abrupt disconnect from the other side.
62 In case of a graceful disconnect from the other side, the backend will, by default, also

38 * Time is a 64 bit unsigned value, representing time in microseconds since boot.
39 * Port is the GPIO port number starting from 0 (for a nrf52833: 0 or 1).
40 * Pin is the pin number in that port (for a nrf52833: 0..31 for port 0, and 0..9 for port 1)
